In Italy all documents,records and family history are in the town of origin. There is not record of the surname Alvatroni in Italy at this time but there are 105 Mosco in Italy with 50% located in the veneto region of the North east part of Italy. Can you furnish any additional information. There is no record of their entry into the USA at ellis Island. Did they die after 1963? Have you filed form 81 with NARA for their entry into any port of the USA. Please get back so that I can send you forward. Peter.
